TYPEWBITING MACHINE.

Application filed June 19, 1922. Serial No. 569,422.

made in two parts; to wit, a base-piece, to

which the machine is attachable, and which may serve as a base-board in the operation of the machine, and a cover which may be set down over the base-piece, for transportation of the machine within the casing.

An object of the invention is the provision of connecting means between the machine and the base-board, whichconnecting means becomes automatically effective in the act of positioning the machine on the board, and.

I in which connecting means there can be no loose play, regardless of wear and tear on the parts. 3 y j 1. feature of the invention is the provision of a base-piece or board, and of anchors thereonfor the machine, of such construction, and so united, as effectively to resist all strains tending to loosen the same, whether such strains occur in the handling of the casing, with the machine therein, or in the application of pressure to set the machine against loose p ayon the base-board. I

In the preferred embodiment of theinvention, the machine rests on rubber feet on the board; and anchors, in the form of hooks fixed to the board for engagement with pins on the machine-frame, are shaped to cam down the machine-frame, against the resistance of the yieldable feet, in the act of moving the machine over the board to bring the pins thereon under the hooks; so that, when the machine is finally positioned, the rubber feet, being under compression, eliminate all play between the hooks and the pins, and take up all play which may arise from wear. By making the casing-base-piece or board of sheet-metahthe connections may be of a nature to resist the strains tending to loosen the same, due to the pressure of the rubber feet, or to handlingof the casing.

Other features and advantages willhereafter appear. i In the accompanying drawings,

Figure 1 is a view, in side elevation, partly cross-sectional, on the linef11 of Figure 2, of the machine-casing; the machine-frames being broken away in parts. Figure 2 is a plan view of the machine frames on the casing-base-plate; the outer frame being broken away, at 'certajinpoints thereof, to show the" connections for the same.

Figure 3 is a detail view, on the line 22 of Figure 2, showing one of the connections of the inner machine-frametothe casingbase-plate.

,Referring to the drawingsthe machine is shown as having an inner frame and an outer frame 11; the latter beinga false or ornamental frame. The type-keys are indicated at 12 and the platen at 13. The innerv frame comprises side plates 14, having flanges 1.5,oll's'et toward'each other at their lower edges. Two cross pieces or tieslfiand 17 connect: the flanges of the side plates, and are secured thereto by screws 18." The outei frame 11 is secured totthe inner frame by screws 19. i i

The casing comprises a base-plate 20, preferably of aluminum or other sheet-metal, having side strips 21, of wood, secured thereto by screws 22, and extending along the periphery thereof Thecasing also comprises a covenportion 23,indicated in dotted lines in Figure 1; which cover-portion fits over the edge-pieces 21'of the base-plate. For supporting the machine on the base-plate, front and rear feet 24 and25, preferably of rubber, are provided. These feet have countersinks 26 to receive the heads of screws27, which pass through the feet, through spacing pieces or washers 28, and are threaded into ears 29 on the flanges 15 on the side plates 1%- of the inner frame. These feet may serve to support the machine on any desk or platform when the casing-base-piece is not employed.

The machine is, however, securely and detachably anchored to the casing-base-piece by the following means. At each side of the machine, below the flanges 15, nuts 30 have their heads riveted to the casing-plate 20. Screws 31 pass through the flanges 15 and thread into the nuts 30, thus holding the machine to the casing, forward of the center thereof. At the rear of the center, ears 32, one at each side of the machine, are secured by screws or rivets 33 to the casing-plate 20. Horizontal slots 34 in the ears 32 cause the latter to assume the form of books. Depending from and struck out of the flanges 15, at the lower edges of the side plates of the inner frame (see Figure 3), are ears 35, one at each side of the machine, adjacent the ears 32, when the machine is in place in the casing. Each ear 35 carries a pin 36, adapted to be slipped into the corresponding slot 34 in the ear 32 in positioning the machine. In order that the pins 36 may more easily find their positions in the slots 34, the edges of the ears 32 are inclined or tapered at 37 and 38, to guide or cam the pins into the slots proper.

.In positioning and securing the machine in place upon the casing-base-piece 20, it is first set down'over the latter, with its feet 24 and 25 resting thereon. It is then pressed down on the casing-base-plate compressing the rubber rear feet and in that condition is moved rearward until the pins 36 are enabled to enter underneath the hooks and are stopped at the rear ends of the slots 34 in the ears 32. I

It will be noted that, due to the resiliency and compressibility of the rubber rear feet 25 of the machine, the latter will yield slightly, to permit entry of the pins 36 into the slots 34, underthe camming action of the inclined faces of the edges 37 and 38of the hooks 32, and will thereupon hold the ma{ chine against. rattling or loose movement at the hooks or pins." Furthermore, the upward pressure of the compressed resilient feet maintains the engagement between the pins and hooks tightly, thereby insuring the continuance of a tight engagement between them despite any wear of the parts that may occur during their use. In this position, the openings for the screws 31 in the flanges '15 on the machine are in registration with the threaded openings in the nuts 30. The screws are then put into place and turned home, anchoring the machine in this position on the base-plate 20 being of metal, and

the connections for the machine being riveted thereto, such connections will not be loosened by the weight of the machine in any handling to which the casing, with its enclosed machine, will ordinarily be subjected. Means, not shown, but which are well known in the art, are provided for securing the base-piece to the cover-portion of the casing, and a handle on the cover-portion may be provided for carrying the casing with the machine enclosed therein.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, 1 claim:

l. The combination of a typewriting machine, a frame therefor having side flanges, compressed resilient feet for the machine, pins ii said side flanges, a detachable baseplate on which the feet are placed and under compression between the machine and baseplate, hooks on said base-plate and hooked on said pins and in tight engagement therewith, said tight engagement between the pins and hooks retaining said compression of the feet, and said compression maintaining said tight engagement between the pins and hooks and therefore preserving the tight engagement between the machine and base-plate, and means for anchoring the ma chine to the base-plate in the above-stated tight engagement condition between the pins and hooks and machine and base-plate.

, 2. The combination of a typewriting machine, a frame therefor, pins projected therefrom, compressible resilient feet on themachine, a detachable base-plate on which the feet are placed, hooks on the base-plate for engagement with the pins when the machine is pressed down on the base-plate, compressing the resilient "feet and the machine when shifted rearward on the base-plate, and bringing the pins and hooks into tight engagement with each other, and means con- 'necting the machine and base-plate with said feet under said compression and the pins and hooks in sald tight engagement with each other.
